中文摘要 |
本文讨论了同时含有具范数约束的非结构式摄动和线性相关系数摄动的闭环系统的鲁棒稳定性,首先给出了一种顶点-棱边型判据,然后引入了顶点相位差的概念,使得这类系统的鲁棒稳定性可以用顶点相位差来精确判断。最后介绍了求取顶点相位差的一种简单算法。 |
英文摘要 |
In this paper we discuss the problem of the robust stability of closed-loop systems with both normbounded unstructured and linearly dependent coefficient perturbations. At first a vertex-edge like criterion is given. Then we introduce the concept of the phase difference of extreme points. By this concept the robust stability of system discussed can be exactly determined. Finally, a simple algorithm for calculating the phase difference of extreme points is presented. |
